Thank you for your support.
There is already a feature request for 5.1 surround support.
Please vote on that one, we will close this one so not to create more duplicates.
Please keep feature requests separate and post them in the Studio One Feature Requests Category.
Please create a new request with Video Thumbnail Tracks as your title.
For your Quantum FP8 Idea, put that FR in General Feature / Product requests.
Please explain (in as much detail with mockups if possible) in your post to get the greatest level of visibility to the developers.
